Which of these 3 racquests? Help me please

Hi, i am a beginner in tennis .i wanna buy a rather good racquet , so i can use it for at least 2 years. But , i don't know much about them. Could you help me which of these 3 racquets would be best for me ?(or any other recommendations would be welcome) And please make some comparison. And the last question: would a wrong choice of racquet slow down the learning of a guy at the beginning level, like me?
Thanks for your help..
